[0049] For installation of existing tire pressure sensors on wheels, see Figure 1 The figure shows the structure of the side of the existing tire pressure sensor. When assembling and fixing the sensor body 1 and the mounting bracket 2, first align the sensor body 1 and the mounting bracket 2 and slide them relative to each other in a direction perpendicular to the paper surface for preliminary positioning. Then, screw in the screws 3 on both sides of the top and tighten them to fix the sensor body 1 and the mounting bracket 2 relatively to complete the assembly of the two.

[0050] For the above assembly operation, before the sensor body 1 and the mounting bracket 2 are slid relative to each other for preliminary positioning, it is necessary to ensure that the sliding matching structures on the sensor body 1 and the mounting bracket 2 are aligned with each other, and before screwing in the screws 3, it is also necessary to ensure that the holes on the mounting bracket 2 and the sensor body 1 are aligned with each other. These alignment requirements will make the operation more difficult and cumbersome. In addition, during disassembly and assembly, a screwdriver is required to operate the screw 3 to screw in or out. For users who do not have a screwdriver tool at hand, they cannot complete the disassembly and assembly by themselves, and the screws are easy to fall off and lose during the disassembly and assembly process, affecting the user experience.

[0051] In response to the above-mentioned problems, the present application utilizes the characteristics of the mechanical dead point and performs a special structural design on the bracket so that it can self-lock on the mounting device after being subjected to force and crossing the dead point of the mounting device (such as the sensor body) through deformation, thereby achieving assembly fixation with the mounting device.

[0052] Based on this, according to one aspect of an embodiment of the present application, a quick-release bracket assembly is provided, which can not only be used for fixing or supporting electronic devices such as tire pressure sensors, smart wearable devices, mobile terminals, but also can be used for mutual assembly between mechanical parts.

[0053] First see Figure 2 and Figure 3 , Figure 2 The three-dimensional structure after the quick-release bracket assembly is connected to the mounting device is shown in the figure. It should be noted that the mounting device is a sensor body of a tire pressure sensor as an example for illustration, which does not constitute a limitation on the specific implementation method of the mounting device. Figure 3 The side structure of the quick-release bracket assembly is shown in FIG.

[0054] like Figure 2 and Figure 3 As shown in the figure, the quick-release bracket assembly 100 includes: a first bracket 110 and a second bracket 120. The first bracket 110 and the second bracket 120 have the same structure, and both include a contact plate 131 and a clamping plate 132 that form an acute angle α with each other. The free end of the clamping plate 132 is provided with a clamping hook 1321. Figure 3 The mirror surface indicated by the dotted line is arranged in mirror symmetry, and the free end of the abutting plate 131 on the first bracket 110 and the free end of the abutting plate 131 on the second bracket 120 are arranged facing each other.

[0055] Based on the above structural design, for the assembly between the quick release bracket assembly 100 and the installation equipment, please refer to Figure 4 The stereoscopic perspective and Figure 5The figure takes the sensor body 200 in which the installation device is a tire pressure sensor as an example. On both sides of the top of the sensor body 200, bosses or connecting shafts for hooking with the hook 1321 can be pre-set. Of course, grooves for the hook 1321 to extend into and hook can also be pre-set on the two opposite sides of the sensor body 200. First, hook the hooks 1321 on the first bracket 110 and the second bracket 120 to the sensor body 200 from both sides. After hooking, since the abutment plate 131 and the clamping plate 132 form an acute angle, when the first bracket 110 and the second bracket 120 are pressed against the sensor body 200, the abutment plate 131 will abut against the edges on both sides of the bottom of the sensor body 200 to form a shape as shown in the figure. Figure 5 At the dead points A and B shown in FIG. 2 , slight pressure will not be able to make the first bracket 110 and the second bracket 120 buckle onto the sensor body 200 .

[0056] Therefore, in Figure 5 Based on the state shown in the figure, it is necessary to apply a large pressure to the first bracket 110 and the second bracket 120 so that the edges of the abutting plate 131 and the bottom of the sensor body 200 are squeezed and deformed, so that the abutting plates 131 on the first bracket 110 and the second bracket 120 respectively cross the dead points A and B and fit on the bottom of the sensor body 200, forming Figure 6 In the state shown, since the hook 1321 is hooked and matched with the top of the sensor body 200, the first bracket 110 and the second bracket 120 can only rotate relative to the sensor body 200 with the hooking point as the axis, and the abutment plate 131, which is set at an acute angle to the clamping plate 132, will be restricted by the bottom of the sensor body 200 and cannot rotate when it is in contact with the bottom of the sensor body 200. In summary, under the mutual cooperation of the hook 1321 hooked with the top of the sensor body 200 and the abutment plate 131 in contact with the bottom of the sensor body 200, the first bracket 110 and the second bracket 120 are respectively self-lockingly fixed on both sides of the sensor body 200, thereby realizing assembly and fixation with the sensor body 200.

[0057] On the contrary, when disassembling, the free end of the abutment plate 131 can be gripped with fingers and a pulling force can be applied outward to rotate the first bracket 110 and the second bracket 120 and the abutment plate 131 can cross the above-mentioned dead points A and B in the opposite direction. Then, the sensor body 200 can be easily separated from the first bracket 110 and the second bracket 120, thereby realizing easy disassembly of the sensor body 200.

[0058] Some installation devices need to be installed on a carrier, for example, the sensor body 200 needs to be installed on a wheel hub to detect tire pressure. Figure 7As shown in the figure, the quick-release bracket assembly 100 may also include a strap 140, and a connecting hole 150 is opened at the adjacent position of the abutment plate 131 and the clamping plate 132. The strap 140 passes through the connecting hole 150 on the first bracket 110 and comes out of the connecting hole 150 on the second bracket 120, and is then tied to the wheel hub 400. On the basis that the first bracket 110 and the second bracket 120 are respectively fixedly connected to the sensor body 200, the abutment plate 131 is pressed against the wheel hub 400 by the strap 140 so that the sensor body 200 can be fixed to the wheel hub 400.

[0059] In addition to fixing the sensor body 200 to the wheel hub 400, the smart wearable device generally needs to be installed on a specific part of the human body to achieve the corresponding function. By tying the strap 140 to the corresponding part of the human body, the smart wearable device can also be installed and fixed on the human body.

[0060] The quick-release bracket assembly 100 can also be used as a connecting bracket for electronic devices. For electronic devices that need to be fixed and installed to work, and also need to be frequently disassembled for charging or battery replacement (such as monitors, video doorbells, etc.), a fixed structure (such as screws, rivets, etc.) is generally provided on a carrier such as a wall or ceiling, and a detachable connecting bracket is provided on the electronic device body. During installation, the electronic device body and the connecting bracket are first assembled and fixed to each other, and then the connecting bracket is fixedly connected to the fixed structure on the carrier, so as to achieve the installation and fixation of the electronic device body on a carrier such as a wall or ceiling. When the quick-release bracket assembly 100 provided in an embodiment of the present application is used as such a connecting bracket, the user can easily complete the assembly and disassembly between the connecting bracket and the electronic device body without tools.

[0061] In addition, if the installation device is a mobile terminal, the quick-release bracket assembly 100 can also be used as a support bracket for tilting or vertically supporting the mobile terminal. In this case, the strap 140 is not required. Instead, a raised support member can be set on the side of the abutment plate 131 of the first bracket 110 or the second bracket 120 that is away from the mobile terminal. For example, it can be a support block, a support rod, a support plate, etc. On the basis of the first bracket 110 and the second bracket 120 being respectively buckled and self-locked on both sides of the mobile terminal, after the first bracket 110, the second bracket 120 and the mobile terminal are placed on the desktop as a whole, the support member abuts against the desktop at the back to place the mobile terminal on the desktop in a tilted or vertical state. Of course, the desktop can also be other planes for placing mobile terminals.

[0062] In addition to the above application scenarios, the quick-release bracket assembly 100 can also be used for assembly between mechanical parts. For example, the first bracket 110 and the second bracket 120 can be used as connecting components to assemble two mechanical parts together.

[0063] To summarize, in the quick-release bracket assembly 100 provided in the embodiment of the present application, the abutment plate 131 and the clamping plate 132 on the first bracket 110 and the second bracket 120 are arranged at an acute angle to each other, and a hook 1321 is arranged at the free end of the clamping plate 132, so that the hooks 1321 on the first bracket 110 and the second bracket 120 are first hooked onto the installation device from both sides respectively, and then the first bracket 110 and the second bracket 120 are pressed so that the abutment plate 131 crosses the dead points at the edges on both sides of the bottom of the installation device, so that the first bracket 110 and the second bracket 120 can be easily fixedly connected to the installation device and self-locked, and the reverse operation can be performed for disassembly. The entire disassembly and assembly process does not require the aid of tools, which is easy and labor-saving with high efficiency.

[0064] According to another aspect of the embodiment of the present application, a tire pressure sensor is provided. Figure 7 The tire pressure sensor 300 includes a sensor body 200 and a quick-release bracket assembly 100 in any of the above-mentioned embodiments. After the first bracket 110 and the second bracket 120 are fixedly connected to the sensor body 200, the abutment plate 131 is pressed against the wheel hub 400 through the strap 140, so that the sensor body 200 is installed and fixed on the wheel hub 400, thereby realizing the monitoring of the tire pressure of the automobile tire.

[0065] In order to enable the quick-release bracket assembly 100 to better fix the sensor body 200 on the wheel hub 400, as shown in FIG. Figure 8 As shown in the side structure of the tire pressure sensor 300 when it is fixed to the wheel hub 400, the bottom of the sensor body 200 is in a concave arc shape, that is, Figure 8 From the perspective shown, the bottom of the sensor body 200 is an arc surface with an upward concave middle area. Correspondingly, the abutment plate 131 is an arc shape that fits the bottom of the sensor body 200. After being set in this way, the abutment plates 131 on the first bracket 110 and the second bracket 120 form an arc that matches the outer periphery of the wheel hub 400 on the side facing away from the sensor body 200. Therefore, after the side of the abutment plate 131 facing away from the sensor body 200 is fitted on the wheel hub 400 through the strap 140, the abutment plate 131 is tightly fitted to the wheel hub 400, and the two have a larger contact area, thereby improving the stability and reliability of the tire pressure sensor 300 installed and fixed on the wheel hub 400.

[0066] Regarding the connection between the hook 1321 and the sensor body 200, Fig. 9 As shown in the exploded structure of the tire pressure sensor 300 , bosses 210 may be provided on both sides of the top of the sensor body 200 , and the hooks 1321 are hooked on the bosses 210 .

[0067] By setting bosses 210 on both sides of the top of the sensor body 200, when the first bracket 110 and the second bracket 120 are connected to the sensor body 200, the hook 1321 can be easily aligned and hooked with the boss 210, which is beneficial to the convenience of assembling the first bracket 110 and the second bracket 120 with the sensor body 200.

[0068] Furthermore, in order to prevent the hook 1321 and the boss 210 from breaking due to excessive squeezing when the quick-release bracket assembly 100 and the sensor body 200 are assembled, Fig.10a The state where the middle hook 1321 is just beginning to engage with the boss 210 and Fig.10b As shown in the state where the hook 1321 is hooked with the boss 210 after the assembly is completed, the hook 1321 itself can form an acute angle β, and the two opposite sides of the boss 210 can form an acute angle θ, β>θ. Fig.10a When the hook 1321 is initially hooked with the boss 210 and rotated counterclockwise for assembly, since β>θ, there is a certain gap C between the inside of the hook 1321 and the left side of the boss 210, and the gap C forms a space for the hook 1321 to rotate, so that the hook 1321 rotates to Fig.10b During the process of the state shown, no excessive extrusion and deformation will occur between the hook 1321 and the boss 210, ensuring that the hook 1321 and the boss 210 are not easily extruded and broken when assembled. Fig.10b As shown, after the assembly is completed, similarly, there is a certain gap D between the inside of the hook 1321 and the right side of the boss 210. The gap D can provide a clockwise rotation space for the hook 1321 when disassembling the quick-release bracket assembly 100, so as to ensure that there is no excessive extrusion and deformation between the hook 1321 and the boss 210 during disassembly.

[0069] The first bracket 110 and the second bracket 120 cooperate with the sensor body 200 through the hook 1321 and the abutment plate 131. Fig. 9 The directions indicated by the double arrows X and Z form a stable limit fixation, and Fig. 9 In the direction indicated by the double arrow Y, if there is no other component to limit the position, the first bracket 110, the second bracket 120 and the sensor body 200 can only be limited by friction, and their stability will inevitably be greatly reduced.

[0070] In this regard, the present application further performs a limiting design on the first bracket 110 and the second bracket 120 in the direction indicated by the double arrow Y. Specifically, Fig. 9As shown in the figure, limit parts 220 can be set on both sides of the boss 210, and the limit parts 220 are used to abut against both sides of the hook 1321 to limit the sliding of the hook 1321 relative to the boss 210 along the direction indicated by the double arrow Y. Based on the limitation of the hook 1321 and the abutment plate 131 in the direction indicated by the double arrow X and the double arrow Z, the quick-release bracket assembly 100 and the sensor body 200 are fixed in three-axis directions, which fully ensures the stability of the connection between the sensor body 200 and the quick-release bracket assembly 100.

[0071] When the tire pressure sensor 300 is installed on the wheel hub 400, the first bracket 110 and the second bracket 120 are generally connected to the sensor body 200 first, and then the strap 140 is passed through the connection hole 150, and finally the strap 140 is tied to the wheel hub 400 to complete the installation. Considering that after the free end of the strap 140 is passed through the connection hole 150 on the first bracket 110, it is easy to cause the free end to hit the internal structure and fail to pass through the connection hole 150 on the second bracket 120 smoothly.

[0072] In order to allow the strap 140 to be easily and smoothly inserted, the present application also designs a structure for guiding the strap 140. For details, please refer to Fig.11 At least two parallel convex strips 230 are provided at the bottom of the sensor body 200, and the abutment plate 131 is attached to the bottom of the convex strips 230. The two ends of the convex strips 230 are respectively facing the connecting holes 150 on the first bracket 110 and the second bracket 120, so that a channel 240 for the strap 140 to pass through is formed between the at least two convex strips 230.

[0073] Specifically, when there is only one strap 140, the convex strip 230 can be as follows: Fig.11 As shown, there are two convex strips 230 respectively located on both sides. For the method of using multiple straps 140 to cooperate with each other for binding, the convex strips 230 can be multiple and parallel to each other, and a channel 240 for a strap 140 to pass through is formed between two adjacent convex strips 230.

[0074] By setting at least two parallel protrusions 230 at the bottom of the sensor body 200 and fitting the abutment plate 131 to the bottom of the protrusion 230, the strap 140 inserted into the connecting hole 150 can be easily and smoothly passed through another connecting hole 150 under the guidance of the protrusions 230 on both sides, thereby realizing convenient installation of the tire pressure sensor 300 on the wheel hub 400.

[0075] For the specific structure of the sensor body 200, please refer to Fig.12The sensor body 200 includes a circuit element 250, a shell 260 and a baffle 270. A mounting opening 261 is provided at the bottom of the shell 260. The circuit element 250 is installed inside the shell 260 through the mounting opening 261. The baffle 270 is provided at the bottom of the shell 260 and covers at least part of the mounting opening 261. The abutment plate 131 is attached to the bottom of the baffle 270, and the strap 140 is passed between the baffle 270 and the abutment plate 131.

[0076] Considering the harsh working environment of the tire pressure sensor 300, in order to improve the waterproof, dustproof, heat-insulating, and vibration-resistant properties of the circuit element 250, the circuit element 250 is generally installed inside the shell 260, and then the circuit element 250 is wrapped and fixed by injecting glue from the installation port 261 to ensure the reliability of the circuit element 250. Usually, after injecting glue, the stability of the circuit element 250 can be ensured without providing an additional baffle at the installation port 261. In addition, in order to improve the stability of the tire pressure sensor 300 installed on the wheel hub 400, the strap 140 usually selects a metal strap with higher structural strength. It has been found through practical tests that when the strap 140 uses a metal strap and no additional baffle is provided at the installation port 261, after the tire pressure sensor 300 is installed on the wheel hub 400, when the wheel hub 400 rolls, the strap 140, due to the action of centrifugal force, the part located on the inner side of the abutment plate 131 will arch toward the inside of the shell 260, forming a Fig.13 The state shown in the middle cross-sectional structure may cause friction and collision between the binding strap 140 and the adhesive layer in the housing 260 or even the circuit element 250 , thereby affecting the stability of the circuit element 250 .

[0077] Based on this, a baffle 270 is provided at the bottom of the shell 260 to close at least part of the installation opening 261, and the strap 140 is passed between the baffle 270 and the abutment plate 131, so that when the strap 140 has a tendency to arch toward the shell 260 due to the action of centrifugal force, the baffle 270 can limit the arching of the strap 140 to ensure that the strap 140 will not damage the rubber layer inside the shell 260 and the circuit element 250.

[0078] In order to facilitate the assembly of the sensor body 200, as Fig.12 As shown, a latching protrusion 262 can be provided on both sides of the shell 260, and a buckle 271 can be correspondingly provided on both sides of the baffle 270. After the circuit element 250 is installed and fixed in the shell 260, the baffle 270 can be pressed to engage the buckle 271 with the latching protrusion 262, and the baffle 270 can be easily fixed and assembled on the shell 260 and at least part of the installation opening 261 can be closed, which is beneficial to improving the assembly efficiency of the sensor body 200.

[0079] On the basis that the baffle 270 is assembled by snapping the buckles 271 on both sides with the buckle projections 262 on both sides of the housing 260, considering that the buckles 271 protruding from the side will affect the installation of the first bracket 110 and the second bracket 120, Fig.12 As shown in FIG, the snap plate 132 is provided with a position avoidance hole 1322, which is communicated with the connection hole 150. When the abutment plate 131 is attached to the bottom of the baffle 270, that is, after the first bracket 110 and the second bracket 120 are fixedly connected to the sensor body 200, the buckle 271 can be as shown in FIG. Fig.14 As shown, it is accommodated in the avoidance hole 1322 .
